“I believe that animals have rights which, although different from our own, are just as inalienable. I believe animals have the right not to have pain, fear or physical deprivation inflicted upon them by us. Even if they are on the way to the slaughterhouse, animals have the right to food and water and shelter if it is needed. They have the right not to be brutalized in any way as food resources, for entertainment or any other purpose. … Finding a substitute for animals in research has only recently become an imperative in the scientific community. … One day animals will not be used in the laboratory. How soon that day comes depends on how soon people stop screaming and make the search for alternatives a major research imperative. As long as conferences on the subject sound like feeding time in the monkey house, monkeys along with millions of other animals are going to stay right where they are now — in the laboratory.”

“God has given to Man an absolute right to take the lives of other animals, for any reasonable cause, such as the supply of food; but He has not given to Man the right to inflict pain, unless where necessary.”

“What I had learned about human rights proved to be directly relevant to my thinking about animal rights. Whether any animals have rights depends on the true answer to one question: Are any animals subjects-of-a-life? This is the question that needs to be asked about animals because this is the question we need to ask about us.”

“Many dogs, cats and horses are loved and cherished, and are even mourned when they die. But pigs, chickens, calves and other animals grown in factory farms are treated in the most brutal and exploitative way, devoid of all affection. They are units in a production line; their only purpose is to produce the maximum amount of food at the minimum cost. Factory farms epitomize the mechanistic spirit. … To justify this treatment, the less-favoured animals have to be regarded as inferior, unworthy of any sentimental attachment. A terrible conflict arises if the exploited animals are considered to have any value in themselves. One way to avoid this conflict is to keep the privileged and the exploited animals in separate categories in our minds. … But if emotions spill over from pets to other animals, there is trouble. People become vegetarians, or even animal rights activists.”

“Animals have their own rights. We’re animals too.”

“I admit it as an axiom, that every animal has more right to the use of its own body than others have to use it.”

“Animals are no one’s property, and they have the right not be ‘taken,’ ‘harvested,’ or ‘culled’ or any other euphemism for murder that wildlife managers use. They are no one’s property, just as you and I are no one’s property other than our own.”

“Have the lower animals "rights?"”

“Have the lower animals "rights?" Undoubtedly—if men have.”

“I think using animals for food is an ethical thing to do, but we've got to do it right. We've got to give those animals a decent life and we've got to give them a painless death. We owe the animal respect.”
